Bread crumb - Simple use of "You are here:" with BreadCrumbTrail. People should understand that! Also notice lack of clutter in the header.

Formating variables - Use of defined variables for quick formating of pictures, comments and other things. See the varible definitions here. (You actually have to use the "raw" view to see the actual coding because it is hidden from "view" mode.)

Nice, readable fonts

Title and subtitle - These are defined in the Title form and invoked by the view template. The title form can be used optionally for custom titles or subtitles - I use it at the homepage and with listings where I add "Index" as subtitle. -- ArthurClemens - 28 May 2003

Use of icon beside links to designate external links.

"Enhanced wiki words" - allows wiki words to be formed by use of underline. Did this require code modification? Yes, I changed TWiki.pm at several places, and I changed SpacedWikiWordPlugin. I also kept the original WikiWord syntax, so they can be used interchangeably. -- ArthurClemens - 28 May 2003

Having "Printable" and "Edit" links at top of page. I would use icons to make them less conspicuous.

Good use of "catagory topics" for organizing topics. Gives me an idea for having a catagory topic template that includes search for topics with that catagory and form to create new topics for that catagory.

Some non-TWiki ones, for inspiration:

http://picogui.org/ A Wiki on the ZWiki (Zope) engine. Nice use of CSS for the "tabs". The tab metaphor is interesting for the "edit", etc, since it conveys the feeling that you are handling the same page, but from different viewpoints, which seems quite intuitive. Note that some parts are non-functional with old browsers (netscape 4). The "Tooltips" popping up when you fill form fields are nice from a UI point of view, and are expansed to static text on old browsers, nice trick even if maybe potentially troublesome. -- CN

(rhk) Wikipedia — added for its diff display which makes it easier to find changes. Three notes:

The diffs are shown by colored text (the first time someone told me Wikipedia had "word diffs", I apparently viewed the page with a CSS style sheet that made all text black, so I didn't see the changes).

The "word diffs" are not quite what I'd like to see, or what I'd call word diffs (I prefer to see one copy of the text with added text underlined (for example), and deleted text hashed out.

I chose this particular example because it seems to show that the "sync algorithm" is not that good — it appears that insertion of one heading (and breaking of one paragraph) prevented the algorithm from recognizing that the following paragraph was the same (or at least the first sentence was the same) as the old version. -- RandyKramer - 05 Jun 2003
